Abstract (en)

[origin: WO2006078767A1] The invention provides a hearing protection device having an attenuating body composed of an elastomer with an increased glass transition temperature and a reduced glass-to-rubber transition temperature such that the damping factor of the material peaks at a higher temperature and, resultantly, the damping factor is increased over a range of temperatures and frequencies typically experienced by the device during usage. The increased damping results in higher sound attenuation provided by the hearing protection device.
